So far it allows you to fix the first row if desired as header, sort your data (sort is string based, so 11 will appear before 2, for example) but I think most interestingly to format it with an arbitrary string... for example you could format your data using something like: <a href="{1}">{0} - {2}</a> for some data where the column 0 is the index, 1 is the url and 2 is the name.

I'll be working on a page to describe the example with actual data but in the mean time I'm open for feedback

I think allowing the possibility to assign types to columns for the sort would be good, but I'll only do it if people are interested in the plugin

I like your plugin idea! Unfortunately it is not working for my test case. Any command results in "csv: The buffer doesn't appear to be a CSV file". I think the plugin assumes the delimiter to be ',' but my test uses ';' (which is valid as far as i know). Furthermore, each data column is placed into double quotes, and can contain ',' or ';'. Here is a simple example (including a header):
